IN l/E IV TOR WITNESSES A TTORNEYS UNITED STATES PATENT OFFICE.

WILLIAM BLOOM, OF NEW YORK, N. Y.

ERASER-HOLDER.

Application filed July 16, 1919.

To all whom it may concern:

Be it known that I, WILLIAM BLOOM, a citizen of the United States, and a resident of the city of New York, borough of Man hattan, in the county and State of New York, have invented a new and useful Eraser- Holder, of which the following is a full, clear, and exact description.

This invention relates to eraser holders formed with clamping side plates, and has for an object to provide an improved construction whereby the side plates may be quickly and easily removed for allowing the erasing material to be completely used, and a new one substituted.

Another object of the invention is to provide a holder having a plate formed with a slot whereby the plate may be telescoped over a retaining sleeve.

A further object of the invention is to provide a holder provided with a slotted plate on one side and a plate on the opposite side having a pressed out eyelet co-acting with the slotted plate for holding the erasing material in place.

In the accompanying drawing:

Figure 1 is a side view of an eraser disclosing an embodiment of the invention.

Fig. 2 is a section through Fig. l on line 22.

Fig. 3 is a perspective View, with the respective parts separated, illustrating a slightly modified form of the invention to that shown in Fig. 1.

Fig. 4 is a sectional view similar to Fig. 2, but illustrating the construction shown in Fi 3.

I teferring to the accompanying drawings by numerals, 1 indicates an eraser which may be rubber, the combination of rubber and sand, or other abrading material. The eraser l-is formed in the shape of a disk and provided with a central aperture '2.

This form of rubber has been found very desirable in erasing typewritten matter, but if made of proper size to grasp by the hand it will bend. To prevent bending side plates have been heretofore provided for bracing the central part. As shown in Fig. 2 a side plate 3 is provided which may be of any construction and provided with an aperture through which eyelet 4L passes, said eyelet.

having flanges 5 and 6 on the end. The flange 5 overlaps the body of the eyelet so as to hold the same in place, and flange 6 overlaps the body of the plate 7. The plate Specification of Letters latent.

7 is formed with a pressed out portion 8 to be engaged bythe thumb when the plate 7 is to be removed. This removal may be made by pressure on the pressed out portion in a direction parallel to the side of the eraser l. A slot 9 is provided which accommodates the eyelet 4, but is made of less width than the flange 6, preferably the eyelet 4 is made of such a length that the eraser 1 will be slightly compressed when the plate 7 is forced in position, whereby the plates firmly grip the sides of the eraser and hold the same in proper position for use. After the eraser has been used until it has been reducedin size to a line almost in contact with the plates 3 and 7, plate 7 may be removed by an upward pull of the parts shown in Fig. 1 and the eyelet and plate 3 may then be disengaged thereby allowing the entire erasing material to be effectually used, as the eraser in its reduced size does not need the reinforcing side plates. A new eraser may then be placed on the eyelet and plate 3 after which plate 7 may be reengaged. In this way a supply of erasers may be retained, but only one set of holders or plates 3 and 7 with their retaining eyelet 4.

In some instances it is desired to have a brush in connection with a holder. To provide a brush a slightly modified construction may be used as shown in Figs. 3 and 4. These views disclose a plate 8 formed with an extension or neck 10 having arms 11 and 12 folded around one end of a bunch of bristles 13 whereby a complete brush structure is provided which will not interfere with the operation of the eraser 1. In addition, instead of having a removable eyelet 4 the plate 3' is preferably provided with an integral eyelet l4 projecting therefrom and formed with a bead 6 for receiving the plate 7. If desired plate 3 could be made with an aperture similar to plate 3 and eyelet 4: used without departing from the spirit of the invention.

In using either form of holder a rigid bracing structure is provided for the sides of the rubber or other erasing material while the parts are formed so as to be readily disengaged at any time and for any purpose, as for instance the application of a new eraser.

What I claim is:

An eraser, comprising an abrading member having a central opening, an apertured plate contacting one side of the abrading member, an eyelet carried by the plate at the opening thereof and extending through the opening of said member, said eyelet being provided With a flange at its end, and a second plate contacting the other side of the ab'racling member and provided With a radial slot extending through the periphery of the plate for slidably engaging the plate with the eyelet between its flange and the abrading member, said plate being provided 10 on its outer face With a projection to facilitate its application and removal.

WILLIAM BLOOM.
